Meow, meow,
Few days ago I started working on a simple Wiki where I want to ‘collect’ all documentation on setting up Fediverse services and everything around it in one place.
Still adding new stuff on a daily basis. Hopefully it will be helpful to someone
How to properly do sysadmin 101 for a homelab:
Backup and test restore your shit. Move backups somewhere they wont be destroyed if the primary is.
Secure your shit. Yes, its annoying. Yes, do it anyway. MFA, good unique passwords in a vault, ssh keys, cert bsded auth, firewalls, crowdsec running. If possible, expose nothing directly to the internet. Use a vpn like wireguard to connect to your home instead. It has clients for everything like your phone, laptops/etc.
Those 2 things will put you head and heels above professional sysadmins. If you really sort them out, start applying for jobs. Seriously.
